Splitting Water

Process heat from a high-temperature nuclear reactor can be used to drive a set of chemical reactions, with the net result of splitting water into hydrogen and oxygen. For example, process heat at temperatures in the range 850°C to 950°C can drive the sulfur-iodine (SI) thermochemical process to produce hydrogen with high efficiency. Electricity can also be used to split water, using conventional, low-temperature electrolysis (LTE). An example of a hybrid process is high-temperature electrolysis (HTE), in which process heat is used to generate steam, which is then supplied to an electrolyzer to generate hydrogen. In this paper we investigate the coupling of the Modular Helium Reactor (MHR) to the SI process and HTE. These concepts are referred to as the H2-MHR. Optimization of the MHR core design to produce higher coolant outlet temperatures is also discussed.

Alumina Composite

Water molecule reacts with aluminium when it is immersed in water, which plays a vital role in hydrogen generation process. This process which uses sodium hydroxide as catalyst produces a byproduct alumina and some other scarce ingredients. This byproduct is mentioned as alumina composite powder (ACP). In an attempt of reutilizing and converting it into a matrix material using a resin polymer as a binder, this work investigates the workability of the product produced by alumina composite matrix. The specimen produced by alumina composite matrix has been tested for its desirable strength, namely, tensile strength, elongation under varied thermal conditions, compression test, flexural test with fiber reinforcement and non fiber reinforcement. The nature of crack formation and the plastic behavior of the specimen during test have been analyzed, based on the crack propagation in failure plane in the alumina composite matrix as a high quality alternative for wood and tiles for high class interior decorations. This research explores the effective use of the byproduct alumina composite matrix and its consistent eco-friendly nature.
